SKU: 437166S
The 437166S is a solder-on tank radiator with a 4 inch crankbox that fits 1991-2005 Freightliner and Sterling Truck models, including the Acterra and FL50. It has a 28.75 x 25 x 2.25 inch core (height x width x depth) with a 2 inch inlet and a 2 1/4 inch outlet. It interchanges with 73 other part numbers. For a unit without the crankbox, see 437145P.
Use only green or yellow antifreeze in this radiator. Red antifreeze, or any extended-life (OAT) coolant, voids its warranty. Why coolant type matters
